Plant Diversity in Pinus yunnanensis Forest in Songhuaba Water Protection Area
摘要
Abstract
Diversity of plant communities in undisturbed and disturbed Pinus yunnanensis forests in Song-huaba Water Protection Area, Kunming, Yunnan Province, China was examined with the method of transect investigation. 55 species in 30 families were found in the undisturbed plot. The major species in shrub-herb layer were Myrsine africana and Fragaria vesca. 44 species in 24 families in the disturbed plot, dominated by Myrsine africana , Pyracantha fortuneana , Pogonatherurn crinitum and Ficus tikoua. The average height of the trees in the undisturbed plots was 7. 27 m, and height II to IV occurred commonly ; while tree average height in the disturbed plot was 5. 03 m, and trees with height H were common. In shrub layer, significant differences were found in values of species richness and ACE between these plots (P<0. 05), and very significant differences were found in values of Fisher a index (p<0. 01). In herb layer however, significant differences were found only in individual number between these plots (P<0. 05). Species compositions among the undisturbed transects were close to each other. Ophiopogon bodinieri (IddVal = 0. 875, p = 0. 001) and Rhododendron spiciferum (IndVal = 0. 667 , p = 0. 001) were indicator species for the undisturbed plot, while species compositions among the disturbed transects were not close to each other, and Poa annua (IndVal = 1. 000, p = 0.001), Pogonatherum crinitum (IndVal = 0. 958, p = 0.001), and Leontopodium sp. (IndVal = 0. 861, p = 0. 001) were indicator species for the disturbed plot. It was showed that species compositions of plant community in P. yunnanensis forest had been affected by disturbance, height of trees and diversity of shrub being decreased.关键词
